Lepidoptera: Biology and Taxonomy

Boana hobbsi is a poorly known hylid frog currently placed within the Boana punctata group. Yet, morphological, ecological and bioacoustic traits do not support this placement, with no molecular data being available to date to test this hypothesis. Based on newly collected mitochondrial DNA sequences, morphological data review and field observations, we provide new insight into the phylogenetic relationships, morphological variations and geographic distribution of B. hobbsi. Our findings reveal that B. hobbsi is nested (with strong support) within the Boana benitezi group, recovering once more a polyphyletic Boana punctata group. Supported by this new genetic, morphological and ecological evidence, we propose a new taxonomic arrangement which includes B. hobbsi as a member of the Boana benitezi group. Furthermore, we emphasize the importance of conducting biological inventories in remote Amazonian areas, where many taxonomic and geographic knowledge gaps persist with regards to Amphibian diversity.
